Topic sentence.

Even though the Islamic empire was far more developed and cleaner than the european empire, it did not come to dominate the planet because of bad leadership.

Elaboration

The reason why they had such bad leadership was because the sultan would kill of all their brothers to prevent them from taking over the throne. Also, they killed of their most able sons and cut their connection with the real world to prevent them from being educated.

Examples/Evidence

Suleyman killed of his most able son and killed his brothers.

Shah abbas killed of his sons and his incompetent grandson inherited the throne.

Explanation/analysis

Because they killed of their most able sons, they darkened the future for the empire. The future leaders were incompetent, uneducated and had no idea about the real world. This led to them demolishing the empire from inside and the people started to become mad. Because the future leaders were bad, the empire declined and also, the other future sultans also started to kill their brothers for the throne.
